Objectives: The main objective of this work is to obtain input power factor closer to unity and regulation of output voltage of semi bridgeless AC-DC converter using linear peak current mode control. Methods/Statistical Analysis: Linear Peak Current Mode control technique is applied to Semi-Bridgeless AC-DC Converter in this paper. This technique helps in achieving power factor closer to unity. The output voltage of the converter is regulated at 200V.The prototype is designed for 200W.Simulation results are obtained for 200W using PSIM software(Simulation Software Package) the converter is analyzed under variable load and supply conditions. Findings: At variable load conditions, power factor is maintained closer to unity and output voltage is regulated to 200V. The efficiency for the converter is found to 96% at full load conditions. Application: Battery charging applications.
